Dethatching , Thatch, Power Raking
Dethatching, along with aeration, is essential to maintaining a lush, healthy lawn. Thatch is a layer of built-up plant material between the green top growth and the roots of grass plants. Thatch develops naturally as lawn grasses grow and slough off roots, shoots and leaves. Some thatch helps protect the roots, but excessive thatch prevents moisture, oxygen and nutrients from penetrating the soil.
The layer of thatch that needs to be removedOne problem with a thick layer of thatch is that newly sown seed will root in the thatch layer — not the soil. You can see in the image to the right how there are barely any grass roots that make it to the soil. This isn’t good. Thatch doesn’t provide the same insulation as soil, so the grass roots dry out quickly, and the lawn dies. A heavily thatched lawn dries out faster so you have to water more frequently. Having a properly dethatched lawn will easily save you money on your water bill.
If you’re not sure if your lawn needs to be dethatched, remove a plug of lawn, and measure the layer of thatch between the top growth and the root zone. If it measures more than 1/2″ in depth, you should dethatch the lawn.
In our northern Illinois climate, dethatching should usually be done in late spring, but well before the intense summer heat arrives.
